My Childhood Sweetheart Has Two Faces

[School daily life + romantic comedy + confrontational couple + single female protagonist + no system + no cheat + no rebirth] Shen Qin, a cool and handsome boy at the top level of Jiang University, is a top student, has eight-pack abs, and has a venomous mouth like tempered arsenic. He is nicknamed "The Walking Refrigerator". He thought his college life would be: coding, studying, fitness, and peaceful years. Until the door opens one day—— His childhood sweetheart Chu Yu, who had moved to Shanghai in the second year of high school, was standing at the door dragging his suitcase, smiling like a sneaky fox: "Are you surprised? We will live together in the future." In front of outsiders, she is a 173-year-old girl with a curvy front and back, elegant and dignified. Boys feel weak in the legs and girls feel inferior. Only Shen Qin knows—— This guy picks his feet and plays games at home, swears a lot, makes dirty jokes, and forces him to call her sister every day. "Call me sister and let me hear it?" "No barking." "Then I'll tell the class about your kissing scene." "... Sister." He thought they were just happy enemies since childhood, until one day he discovered that he seemed to have fallen into trouble.
